Revit 2017 - Combine Parameters in a Schedule

This is the often requested ability to concatenate parameters values into a single column. The schedule Properties dialog has seen some cosmetic changes, note the new Combine Parameters button.

We see the new smaller buttons replacing the larger and clearer buttons of old. I also get the New and Modify buttons confused with each other ALL the time. When we use Combine Parameters the dialog looks like this for a Room Schedule.

This is combining width and height into a single size parameter for a Door Schedule.

Another very interesting possibility is to combine different parameters for the same values when different families are displaying the same information but have different parameter names, because they came from different family creators. Here's combining three versions of width parameters into a single column, three families using three different shared parameters for the same thing, you can see I left each parameter's name in the heading.

I found it interesting that I can even combine parameters assigned to different Types of Parameter, like length and text. This is an example where I've combined two text parameters and one length parameter all intending to say the same thing, however impractical it will be to deal with the units of that mixture, or lack thereof.

This means we can create a VAV Schedule based on different families from different manufacturers and combine their different manner of Horsepower (or similar) parameter value into a single column. VERY interesting!
